What is Paradigm
1 • It is the way we perceive, understand and interpret the world.• A paradigm is like a map in our head.• Paradigm is an interpretative framework, which is guided by "a set of beliefs and feelings about the world and how it should be understood and studied." (Guba, 1990).
2 Denzin and Lincoln (2001) listed three categories of beliefs: • Epistemology - To do with our beliefs about how one might discover knowledge about the world• Ontology - To do with our assumptions about how the world is made up and the nature of things• Methodology - To do with the tools and techniques of research
Relationship of the three: Epistemological and ontological positions should have some bearing on the methods that you select for your research
Introduction
Research Paradigm
Positivism Positivism argues that research should act “… as an organised method …” surrounding precise empirical observations of individual behaviour in order to discover and confirm a set of probabilistic causal laws that can be used to predict general patterns of human activity” (Neuman, 1997: 63).
Positivist research gained dominance in the natural sciences and was later adopted in social sciences.
Interpretive The interpretive approach argues that research should explore “…socially meaningful action through the direct detailed observation of people in natural settings in order to arrive at understandings and interpretations of how people create and maintain their social worlds” (Neuman, 1997:68).
We use “… methods that try to describe and interpret people’s feelings and experiences in human terms rather than through quantification and measurement” (Terre Blanche & Kelly, 1999: 123).

The Philosophical Position
Positivist
Ontology: what is the nature of reality?
Reality is objective and singular, apart from the researcher
Epistemology:What is validKnowledge?
Researcher is independentfrom that being researched
Axiology:Role of values
Value free and un-biased
Research Strategy •Experimental•Surveys
Rhetoric: -What is the language of research?
Formal style (e.g. researchers use agrees on definitions of variables)
Methodology: -What is the process of research?
Deductive (e.g. researchers that an a priori theory)
Methods Close ended questions, predetermined approaches numerical data, statistical analysis (Quantitative)
Features of Research Paradigms
PositivistTends to produce quantitative data
Uses large samples
Concerned with hypothesis testing
Data is highly specific and precise
The location is artificial
Reliability is high
Validity is low
Generalises from sample to population

Quantitative Research Is "a formal, objective, systematic process in which numerical data are utilised to obtain information about the world“. It is inclined to be deductive. In other words it tests theory.
What Is Quantitative Research?
To GeneralizeTo Be ObjectivesTo Test Theories or Hypotheses
GENERAL AIMS OF QUANTITATIVE RESEARCH?
Quantitative Research QuestionsTHREE RULES for Quantitative Research Questions 1. They Begin with “How”, “What”, or “Why” ?2. Specify the independent and dependent variables3. Example:• What factors positively impact employee turnover rates of hourly workers?• Why do Asian American students outscore other student groups on AP Calculus Exams?
EXPERIMENTAL
Strategies Associated With Quantitative Approach
Experimental research provides a framework for establishing a relationship between causes and effects. In experimental the researcher acts as a inactive agent and use deductive reasoning to prove or falsify hypothesis. This involves manipulating an independent variable (cause) and observing the outcome on dependent variable (effect) while controlling the extraneous variables. Moreover, random sampling, manipulation and control are the characteristics of the true experiments.
SURVEYSSurveys include cross-sectional and longitudinal studies using questionnaires or structured interviews for data collection, with the intent of generalizing from a sample to a population

Process Of Quantitative Research
2- HYPOTHESIS
1- THEORY
3- RESEARCH DESIGN
4- DEVISE MEASURES OF CONCEPTS
5- SELECT RESEARCH SITE
6- SELECT RESEARCH SUBJECT/ RESPONDENTS
7- ADMINISTER RESEARCH INSTRUMENTS/ COLLECT DATA
8- PROCESS DATA
9- ANALYZE DATA
10- FINDINGS/ CONCLUSIONS
11- WRITE UP FINDINGS/ CONCLUSIONS

The Philosophical Position
Interpretive
Ontology: what is thenature of reality?
Reality is subjective and multiple as seen by the participants
Epistemology:What is validKnowledge?
Researcher interacts with that being researched
Axiology:Role of values
Value-laden and biased
Research Strategy •Case Study•Grounded Theory•Phenomenology•Ethnography•Narrative
Interpretive
Rhetoric: -What is the language of research?
Informal style. (e.g. researchers write in s literary, informal style
Methodology: -What is the process of research?
Inductive (e.g. researchers start with participants views and build “up” to patterns, theories and generalizations)
Methods Open ended questions, emerging approaches, and text and image analysis(Qualitative)
Features of Research Paradigms
InterpretiveTends to produce qualitative data
Uses small samples
Concerned with generating theories
Data is rich and subjective
The location is natural
Reliability is low
Validity is high
Generalises from one setting to another

Strategies Associated With The Qualitative Approach?
NarrativeCase Study
Attempts to shed light on a phenomenon by studying in depth a single case example of the phenomena. The case can be an individual person, an event, a group, or an institution.
Grounded Theory
Theory is developed inductively from a corpus of data acquired by a participant-observer.
PhenomenologyDescribes the structures of experience as they present themselves to consciousness, without recourse to theory, deduction, or assumptions from other disciplines
EthnographyFocuses on the sociology of meaning through close field observation of socio-cultural phenomena. Typically, the ethnographer focuses on a community.
Narrative
A from of inquiry in which the researcher studies the lives of individual and ask one or more to provide stories about their lives and in the end, the narrative combine views from the participants’ life with those of researcher’s life in a collaborative narrative.

Qualitative Research Is “an informal, subjective research approach that usually emphasizes words rather than numbers in the collection and analysis of data” and that is inductive in nature. In other words it generates theory.
The father of Qualitative Research is Norman K. Denzin
What Is Qualitative Research?
GENERAL AIMS OF QUALITATIVE RESEARCH?
To add understanding to a phenomenon or the complexities
of human behavior
It does not claim to generalize
To generate theory therefore it is inductive rather than deductive
Qualitative Research Questions1. Begin with “How” or “What”. Avoid “Why” [this is a quantitative term]2. List the central phenomenon you plan to explore3. Identify the participants and research site4. Example:• What is the role of store managers in employee satisfaction of hourly workers at Staple• How will advisory committee impact giving by senior citizens in town area?
15
Main Steps Of Qualitative Research?
1 .General Research Question
2 .Selecting Relevant Site(s) and Subjects
3 .Collection or Relevant Data
4 .Interpretation of Data
5 .Conceptual and Theoretical Work
6 .Writing up Findings/Conclusions
5a. Collection of Further Data
5b. Tighter Specification of the Research Question (s)
